Research

flower

Most of my research is in improving programmability, reliability and energy efficiency of multiprocessor and multicore systems, among some other distractions. It includes work in architecture, compilers, programming models, operating systems, and some other random areas. I am a proud member of the sampa group.

If you need a good architecture simulator, take a look at SESC, a very fast multiprocessor simulator. And here is a good way of choosing your next architecture or compiler conference.

We have recently reseased our Grappa runtime system for large-scale irregular applications (e.g., graph analytics), take a look!
We have also recetnly started publicizing approxbench.org, a set of tools and benchmarks for approximate computing research.

Take a look at the collectively written white-paper on 21st Century computer architecture research.

I am lucky to have my research supported by Microsoft, Intel, Google, Qualcomm, NetApp, NSF, and the Pacific Northwest National Laboratory. I am also a member of the Center for Future Architectures Research.

I received an NSF CAREER Award and a Microsoft Research Faculty Fellowship to develop ideas on deterministic multiprocessing and multicore programmability in general. I am also the 2013 recipient of the IEEE TCCA Young Computer Architect Award.

In 2008 I co-founded Corensic(former PetraVM) together with Mark Oskin and Peter Godman to commercialize technology initially developed at UW-CSE. I have recently co-founded another company, Konyac, to commercialize some magic we developed recently. More news on that soon.

About me

I was born in São Paulo, Brazil.

I received my PhD in Computer Science from University of Illinois at Urbana-Champaign. I got my BEng and MEng in Electrical Engineering from University of São Paulo, Brazil.

Self portraits.

I love to cook and eat.

I am very fortunate to have such a happy family.

My (much smarter than me) brother is freezing in Michigan but having fun with aerospace engineering.

I am always happy because she exists.
